PreBug Zuma my 1st build

[Zino]

here are some pipes
I run the malossi wild lion and like it alot it pairs well with a sport bbk like your polini .
It gives great take off and a few miles per hour up top.
The polini pipe is a copy alot of pipes are made and then rebadged by some one else .
They are just a notch louder than stock .

The Stage 6 street gets good reviews it has a little throatier sound.
All of these pipes would keep you low 9s for Rpms so are very Crank friendly .

Thanks zino. Hey I figured I'd try the sharpie trick today and I'll post a pic below please tell me if I can get more out of it. I have lots if get up and go but would really like that sweet spot 75 or 80km hour. Is gears the ticket ? And how hard are they to do? Variator pic attached

[Zino]

On the polini high speed you can get travel down to 2mm .
I have run that and the malossi multi var.
Take the shim out of the variator to test if you get better travel.
If you do then get a vaiator shim kit so you can dial in for best take off .

Gears on the zumas are not hard to do .
As long as you no some one with a hydraulic press I got mine pressed in for a 12 pack of coors light and a 12 pack of mountain dew .
They add about 6-8 mph to your top end .
You will still have plenty of wheelie power.
here is the gear swap in pictures

That's not bad travel. 😁
Gears would help. After about 20MPH to variator is fully out and only an increase in revs gets a higher top speed. Without a sports pipe that revs higher. Gears would help.
The stage 6 is supposedly the best performance stealth pipe. But is also the most expensive.

So zino the only thing needing pressing into the shaft is the bearing? The gear just slides on?

[rockyp]

Also what am I looking for when buying ie. Name or ratio idk. Çand approx price?

[Zino]

The way I did it is I went for a good long half hour ride .
Then I unbolted the Gear Cover while it was still warm .
A couple Raps with a rubber hammer and it popped out .
I bought a brand new bearing and had that pressed into the bearing and case by the Shop.
While they pressed the bearing.
Some guys stick the shaft in the freezer and warm the bearing in the oven and Tap it on with PVC.

[Zino]

You can go as low as 11 to 1 is the one most shoot for
To get in that range you need 15/50 gears or 13/44 gears .
I have Straight Cut Gears They sound like a turbo winding up .
The Stock Prebug has 13.228 Gear Ratio
Primary gears is what you switch 80-100 bucks with a bearing

? I totally gapped out and forgot to attach the rpm and head temp gauge when I had the bike apart. Is there anyway to even get access to the plug and wire without full teardown. Seems crazy if you can't service your plug??

[Zino]

Those prebugs are alot more work to get too the spark plug .
No real easy solution .
Just treat yourself to a cold one afterwards .

[Zino]

Last prebug That I helped build up
Had a mild pipe Leo vince zx malossi Sport kit and 11 to 1 gears was High 50's .
Those light scoots are easy to make fast

[aeroxbud]

On mine there is a little hatch in the bucket under the seat. It's held with a screw. Just big enough to change the plug.

I thought I'd post an update guys. Been enjoying the scoot daily and using it hard and steady. Been rock solid and no issues. I received my new headlight bezel and it came with the same lame 20watt halogen but the are a mr16 bulb so I went to my local hardware store and got some cool white 5000k 50 watt equivelent l.e.d.s that only pull 7watts . They are super common 12volts and used for track lighting etc and spotlights in gardens so win win there for 7 bucks I got 3 bulbs and the difference is amazing. Clearly see no problem at all. There are a 2 pin tho so as of now I have no high beams but that suites me fine. Is there a way to wire a 2 pin to 3 pin system? Also the new stealth pipe came in today I got er bolted up and doesn't seem any louder actually I couldn't find a wil lion anywhere that was reasonably close (shipping cost insane) so I got a polini and it definitely has more wheel popping power of the line and on the top end. Can play with traffic now and be a leader instead of everybody waiting on me. So much fun now and really for very little money it's a ultra reliable little screamer. Less than 1500 Canadian pesos total cost. My lady is getting more confident on the typhoon and she's so jealous of me when I pull away that it looks like that's the next build. And recommendations on that unit 2015 piaggio typhoon 4v 4t. Also pics to follow of the new light bezel and pipe and the new mirrors and l.e.d. signal conversion. I think I'm done with the the Zuma now mechanically and just going to paint it up that polini racing style the white n blue and it's done deal. I thank everyone that steered me in the right direction and helped out. Cheers

Nice work She looks sharp.
Those mirrors make it look like a jet
The polini pipe and wild lion are actually the same pipe gianelli makes them for them .
How much faster on the top end are you with the pipe .

I'm not certain 100% yet but the guidelines u set out are very close. I'd say another 3 to 4 mph. I can do 85km\h on speedo and my phone says 80kms. Your the man Zino thanks for all your help. Any recommendations on the piaggio?
